The region escapes with a mainly dry day If there is ever a textbook image to discuss a synoptic storm occlusion, this would be one to use. I’ll define that for the newcomers. Synoptic storms are what are most common around our region. When the term “NorEaster” gets tossed around, that is essentially slang for what these storms are. Whether it is a NorEaster (cold side) or an inside runner / SouEaster (warm side), it’s a synoptic storm. The term occlusion is a meteorological term for weakening. When the dry air enters the core (central low pressure) as this image indicates, the storm is past maturity and, in this case, weakening rapidly. The rex block discussed in Sunday’s post did a great job of diffusing this flare-up.  It will be the tale of two Maines for the day, with northern areas seeing the most sun and the higher, above-normal temperatures, with coastal areas running on the cool side. The result of the rapidly weakening system means less fanfare for rainfall than what was noted in Sunday’s update, which wasn’t much to begin with. Most of the region escapes with a dry day, with only a few isolated showers for the south and the shorelines dealing with patchy fog and drizzle. For experienced surfers, this is one of the best days for the board in a couple of months. For the inexperienced swimmers, this is a day to stay out of the ocean, not like it is a great day for a dip anyway. Shower chances increase overnight into Tuesday Monday 6 PM to Wednesday 2 AM - As the low heads north, the chance for showers, areas of fog, and drizzle overspread the region overnight and into Tuesday. As the HRRR idea suggests, showers are expected to be isolated to widely scattered in a hit-or-miss fashion. The sun may poke out in spots, which may produce an isolated thunderstorm. Dew point temperatures are on pace to juice up in the mid-60s to low 70s, meaning the risk of a dumper is there. While the severe threat is highly unlikely, I can’t dismiss it completely. Warm front moves in on Wednesday Warm fronts are always a concern for this forecaster because they can bring potential surprises with convective activity, and this one will be another to stay mindful of. The Weather Prediction Center’s excessive rainfall outlook for Wednesday indicates the risk of isolated dumpers that could bring localized flash flooding. Depending on how the day evolves will indicate how much of a strong to severe storm threat is realized. Expect the unsettled pattern with the risk of showers and storms to continue through the rest of the week and the weekend as temperatures and humidity continue to rise. There is an indication that the high heat concerns in the longer term are diminishing.    Always have MULTIPLE ways to receive weather alerts.
